I picked up an 81 ram 50 2wd drive a couple weeks ago. It’s got a g54b and stock Mikuni. Truck ram great when I test drove it and on the 70 mile drive home. Now it’s started to develop a rough idle where it nearly dies sometimes. Signs point to a vacuum leak so I’ve been replacing old crusty lines and checking for leaks. I noticed a piece of the carb seems to be missing and I can’t find a diagram that will show me what it is. I did a little spritz of brake clean on it with the truck running and it idled down so I’m guessing it’s the culprit. I just don’t know what it is.
Tried uploading a photo but I’ll have to do it from my computer. Until then, the piece that’s missing is on the intake passenger side of the carb down near the base. It looks like 3 small screws held it on and it had an o ring about the size of a quarter.
I’ll post a picture as soon as I get a chance.
Thanks!
